It has an effect. But it do not set my internal screen the "default" one.
I mean, if I declare "LeftOf", it is as if my external screen is the 
"center"
and my internal screen is at its left.
Reverse effect with RightOf.

But what I want to obtain is my internal screen at "center" and my external
screen at left (or right).
But XOrg/NVidia always put my external screen at the first place in its list
((II) NVIDIA(0): Connected display device(s): CRT-0, DFP-0, where CRT is
my internal screen).

Any idea?
